* - `div` - Either `false` to disable the div, or an array of options for the div.
* See HtmlHelper::div() for more options.
* - `options` - for widgets that take options e.g. radio, select
* - `error` - control the error message that is produced
* - `empty` - String or boolean to enable empty select box options.
* - `before` - Content to place before the label + input.
* - `after` - Content to place after the label + input.
* - `between` - Content to place between the label + input.
* - `format` - format template for element order. Any element that is not in the array, will not be in the output.
* - Default input format order: array('before', 'label', 'between', 'input', 'after', 'error')
* - Default checkbox format order: array('before', 'input', 'between', 'label', 'after', 'error')

/**
* Returns a formatted SELECT element.
*
* ### Attributes:
*
* - `showParents` - If included in the array and set to true, an additional option element
* will be added for the parent of each option group. You can set an option with the same name
* and it's key will be used for the value of the option.
* - `multiple` - show a multiple select box. If set to 'checkbox' multiple checkboxes will be
* created instead.
* - `empty` - If true, the empty select option is shown. If a string,
* that string is displayed as the empty element.
* - `escape` - If true contents of options will be HTML entity encoded. Defaults to true.
* - `value` The selected value of the input.
* - `class` - When using multiple = checkbox the classname to apply to the divs. Defaults to 'checkbox'.
*
* ### Using options
*
* A simple array will create normal options:
*
* {{{
* $options = array(1 => 'one', 2 => 'two);
* $this->Form->select('Model.field', $options));
* }}}
*
* While a nested options array will create optgroups with options inside them.
* {{{
* $options = array(
* 1 => 'bill',
* 'fred' => array(
* 2 => 'fred',
* 3 => 'fred jr.'
* )
* );
* $this->Form->select('Model.field', $options);
* }}}
*
* In the above `2 => 'fred'` will not generate an option element. You should enable the `showParents`
* attribute to show the fred option.
*
